Since I got such fine suggestions for my last TeX problem, I thought I'd
post another.  I posted a similar question a few years ago and got no help!
I'm writing up a proof that requires some manipulation of generators of an
algebraic system.  The proof requires long expressions that get regrouped
in various ways, and in looking at one expression grouped in two different
ways.  I would like to use braces above and below the expression to
identify the groupings.  Something like this:

               p           q 
         |-----------||-----------|
      abcdefgaaaabbbbccccdefghabecde
      |-----||----------||---------|
         x        y          z

where the "|-------|" represent braces.  (This would indicate something
like "xyz = abcpqe".  Done in this way, the proof becomes much more
visual--which really helps for this sort of calculation.)

While I have been able to put the braces on top *or* the braces on the
bottom *or* braces on top and bottom as long as they don't overlap,
the particular configuration I need has eluded me for several years now.

Any suggestions would be received with delight!

Thanks,

--Walter
